DETAILED DESCRIPTION

The following detailed description is merely illustrative and is not intended to limit embodiments and/or application or uses of embodiments. Furthermore, there is no intention to be bound by any expressed or implied information presented in the preceding Background or Summary sections, or in the Detailed Description section.

One or more embodiments are now described with reference to the drawings, wherein like referenced numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a more thorough understanding of the one or more embodiments. It is evident, however, in various cases, that the one or more embodiments can be practiced without these specific details.

With the rise of media publishing and distribution via the Internet, users around the world can access a voluminous quantity of media content (e.g., video and audio content). Further, the popularity of social networking has made sharing media content a highly profitable mechanism to increase viewership and generate revenue. As a result, new and old media content is regularly downloaded, copied and shared with the touch of a button. Given the ease with which media content can be viewed, and in many scenarios copied or downloaded, the task of detecting the unauthorized usage of copyrighted media content via the Internet has become extremely difficult for humans and even basic computer processing systems to perform effectively and efficiently. As used herein, a “copyrighted media item” refers to a media item that cannot be copied, reproduced, published, sold or distributed without authorization from an entity or group of entities associated with ownership of the one or more copyrights for the media item.

The subject disclosure is directed to computer processing systems, computer-implemented methods, apparatus and/or computer program products that facilitate efficiently, effectively, and automatically (e.g., without direct human involvement) detecting usage of copyrighted media content, and more particularly copyrighted video content. For example, usage of copyrighted video content can include the creation of a new video by partially modifying an aspect of a copyrighted video (e.g., changing the coloration, saturation, luminosity, speed). In another example, usage of copyrighted video content can include the creation of a new video using parts of one or more copyrighted videos. In another example, usage of copyrighted video content can include copying, publishing or selling the copyrighted video content without authorization from the copyright holder.

In order to facilitate detecting unauthorized usage of copyrighted video content, one or more embodiments described herein include object matching techniques that involve identifying whether a video includes copyrighted video content based on correspondence between visual objects appearing in the video and the copyrighted video content. In one or more embodiments, a reference digest database is initially generated using automated object recognition for one or more known videos. The one or more known videos are referred to as “reference videos.” In various implementations, the known or reference videos include video content that has been copyrighted or otherwise restricted for usage (e.g., copying, reproducing, publishing, selling, or distributing) by a single entity or a group of entities. The reference digest database includes information identifying the respective reference videos and digest information for the respective reference videos related to the objects appearing in the reference videos. For example, reference digest information for each reference video (or, in some embodiments, one or more reference videos) can include, but is not limited to, information identifying objects present in the reference video, detailed characteristics of the objects appearing in the reference video (e.g., object coloration, object type), an order of appearance of the objects, timing of appearance of the objects, and/or spatial relationships of two or more of the objects included in a same video frame or segment.

Newly identified or received videos can be screened against the reference digest database to determine whether they are or include reference video content. For example, in one or more implementations, digest information can be generated for a new video in the same or similar manner employed to generate the reference digest information for the reference videos. The digest information for the new video is further compared against the reference digest information for the reference videos to identify a match between the content of the new video and the content of the reference videos based on a degree of similarity between the digest information for the new video and the digest information for the respective reference videos. If the digest information for the new video does not satisfy a defined criterion (e.g., meet a threshold value) relative to reference digest information for one or more of the reference videos, the new video and the digest information for the new video can be added to the reference digest database as a new entry. However, if the digest information for the new video satisfies the defined criterion (has a threshold level of similarity or sameness) one or more policies can be automatically enforced that facilitate mitigating the unauthorized usage of the reference video content (e.g., notifying the copyright holder, rejecting or removing publication of the new video, providing a royalty payment to the copyright holder).

The computer processing systems, computer-implemented methods, apparatus and/or computer program products employ hardware and/or software to solve problems that are highly technical in nature (e.g., related to automated detection of correspondence between digital video content and copyrighted digital video content), that are not abstract and that cannot be performed as a set of mental acts by a human. For example, a human, or even thousands of humans, cannot efficiently, accurately and effectively manually analyze the voluminous amounts of new electronic video content shared via the Internet daily to identify whether the video content includes copyrighted video content. One or more embodiments of the subject computer processing systems, methods, apparatuses and/or computer program products can enable the automated detection of copyrighted video content in a highly accurate and efficient manner By employing object recognition and object matching to detect correspondence between video content, the processing time and/or accuracy associated with the existing digital media copyright detection systems is substantially improved. Further, one or more embodiments of the subject techniques facilitate automatically and/or accurately identifying videos that have been modified in an attempt to avoid automated copyright infringement detection. For example, by determining correspondence between timing of appearance of objects in a video and a copyrighted video, one or more embodiments of the object based matching techniques described herein facilitate identifying videos that include copyrighted video content that has been modified. For instance, one or more embodiments of the subject techniques enable detecting videos including copyrighted video content in which the speed of the video content has been increased or decreased, one or more new objects have been overlaid onto the copyrighted video content, coloration has been applied and/or the like.

Further, one or more embodiments of the computer processing systems, computer-implemented methods, apparatuses and/or computer program products facilitate automatically mitigating the unauthorized usage of copyrighted video content. For example, in response to identifying a video that is or includes copyrighted video content, one or more embodiments of the computer processing systems, computer-implemented methods, apparatuses and/or computer program products can automatically reject or remove publication of the video, notify the copyright holder, facilitate provision of a royalty payment to the copyright holder or perform any number of other mitigation functions.

FIG. 1 illustrates a block diagram of an example, non-limiting system 100 that facilitates detecting usage of copyrighted video content using object recognition in accordance with one or more embodiments described herein. Aspects of systems (e.g., system 100 and the like), apparatuses or processes explained in this disclosure can constitute machine-executable component(s) embodied within machine(s), e.g., embodied in one or more computer readable mediums (or media) associated with one or more machines. Such component(s), when executed by the one or more machines, e.g., computer(s), computing device(s), virtual machine(s), etc. can cause the machine(s) to perform the operations described.

As shown in FIG. 1, the system 100 can include a server device 102, one or more networks 124 and one or more digital media sources 126. The server device 102 can include digital media management component 104, which can include reception component 106, digest component 108, and matching component 114. The server device 102 can also include or otherwise be associated with at least one include memory 120 that stores computer executable components (e.g., computer executable components can include, but are not limited to, the digital media management component 104 and associated components). The server device 102 can also include or otherwise be associated with at least one processor 118 that executes the computer executable components stored in the memory 120. The server device 102 can further include a system bus 116 that can couple the various components including, but not limited to, the digital media management component 104 and associated components, memory 120 and/or processor 118. While a server device 102 is shown in FIG. 1, in other embodiments, any number of different types of devices can be associated with or include the components shown in FIG. 1 as part of the digital media management component 104. All such embodiments are envisaged.

The digital media management component 104 facilitates detecting usage of copyrighted media content, and more particularly, detecting usage of copyrighted video content. The term “media content” can include, but is not limited to, streamable and dynamic media (e.g., video, live video, video advertisements, music, music videos, sound files, animations). The term “video” includes, but is not limited to, a sequence of images that form a moving picture. The term “video content” can include, but is not limited to, two or more consecutive moving images or frames of a video, video segments, animations, single images or frames of a video, and portions of one or more images or frames of a video.

The reception component 106 can receive video content for processing by digital media management component 104 to detect reference video content embedded in or associated with another video. For example, reception component 106 can receive reference videos for processing by digital media management component 104 in association with generating a reference digest database 122. The reception component 106 can also receive new videos for processing by digital media management component 104 to determine whether the new videos include reference video content.

In various embodiments, the reception component 106 can receive video content from one or more digital media sources 126. The one or more digital media sources 126 can include an internal media source that is accessible to the server device 102 either directly or via one or more networks 124 (e.g., an intranet) or an external media source that is accessible to the server device 102 via one or more networks (e.g., the Internet). For example, the one or more digital media sources 126 can include a computer-readable storage device (e.g., a primary storage device, a secondary storage device, a tertiary storage device or an off-line storage device) that stores video content. In another example, the one or more digital media sources 126 can include an information store that provides access to digital media data included in the information store via one or more networks 124. In another example, the one or more digital media sources 126 can include a digital media content provider that includes a website or application that provides videos and other types of content items or services to client devices via a network (e.g., the Internet). According to this example, the video content provided by the website or application can be downloaded, streamed or merely viewed at a client device.

In some implementations, the reception component 106 can receive a video that is uploaded to the server device 102 by a client device. For example, the media provider can include a media presentation source that has access to a voluminous quantity (and potentially an inexhaustible number) of shared video files that are uploaded to the media provider by users of the media provider. The media presentation source can further stream these media files to client devices of respective users of the media provider via the one or more networks 124.

In some implementations, the reception component 106 can scan the digital media sources 126 for video content, including reference video content and/or new video content. For example, the reception component 106 can scan various websites, applications, and network accessible storage devices for video content that can provide and/or employ reference video content in an unauthorized manner (e.g., unauthorized usage of copyrighted video content). In various embodiments, the reception component 106 can be or include hardware (e.g., a central processing unit (CPU), a transceiver, a decoder), software (e.g., a set of threads, a set of processes, software in execution) or a combination of hardware and software that facilitates receiving video content from one or more digital media sources 126.

The various components (e.g., server device 102, digital media management component 104 and associated components, digital media sources 126) of system 100 can be connected either directly or via one or more networks 124. Such networks 124 can include wired and wireless networks, including, but not limited to, a cellular network, a wide area network (WAN) (e.g., the Internet) or a local area network (LAN). For example, the server device 102 can communicate with one or more digital media sources 126 (and vice versa) using virtually any desired wired or wireless technology, including, for example, cellular, WAN, wireless fidelity (Wi-Fi), Wi-Max, WLAN, and etc. Further, although in the embodiment shown the digital media management component 104 is provided on a server device 102, it should be appreciated that the architecture of system 100 is not so limited. For example, the digital media management component 104 or one or more components of digital media management component 104 can be located at another device, such as another server device, a client device, etc.

Digest component 108 can generate digest information for one or more videos. The term “digest information” is used herein to refer to one or more visual features associated with a video. Digest information can distinguish the video from one or more other videos and/or identify the video, providing functionality similar to that of a fingerprint. For example, in the field of audio matching, an acoustic fingerprint is a condensed digital summary of audible features deterministically generated from an audio signal that can be used to identify an audio sample or locate similar items in an audio database. A digest or digest information for a video can be likened to an audio fingerprint for an audio signal wherein the audible features are replaced with visual features included in the video. In one or more implementations, these visual features can include, but are not limited to, objects appearing in the video (e.g., persons, places, things). In addition to the objects appearing in the video, digest information for a video can also include, but is not limited to, detailed characteristics associated with the objects (e.g., coloration, type), order of appearance of the objects, timing of appearance of the objects and/or spatial relationships between two or more objects appearing in a same frame or segment of the video. In some embodiments, a segment of a video can include any amount of the video less than the whole video. For example, a segment of a video can include one or more frames of the video (e.g., one frame, two frames, five frames, ten frames) or any selected time segment including one or more seconds or milliseconds of the video (e.g., one second, two seconds, five seconds, ten seconds).

In one or more embodiments, digest component 108 can generate a compilation of reference digest information for a set of known reference videos that have been previously provided or made accessible to the digital media management component 104 (e.g., via reception component 106). For example, the digital media management component 104 can be provided with a voluminous quantity (and potentially an inexhaustible number) of reference videos and generate digest information for one or more of (or, in some embodiments, each of) the reference videos. In various implementations, the reference videos can include video content that has been copyrighted or otherwise restricted for usage (e.g., copying, reproducing, publishing, selling, or distributing) by a single entity or group of entities. In some implementations, the digest component 108 can organize the reference digest information for the reference videos in a reference digest database 122. For example, the reference digest database 122 can include information identifying one or more of (or, in some embodiments, each of) the reference videos and the digest information respectively associated with the one or more of (or, in some embodiments, each of) the reference videos. The reference digest database 122 can be stored at a location that is accessible to the digital media management component 104. For example, in the embodiment shown, the reference digest database is provided in the memory 120 of the server device 102. However, it should be appreciated that the reference digest database 122 can be located at another suitable device that is accessible to the digital media management component 104 via a direct connection or via one or more networks 124.

A digest or digest information for a video can represent the video as a whole and/or can represent slices or segments of the video. For example, a video creator can create a new video by combining pieces or parts of two or more reference videos. For instance, the new video can include a compilation of video segments from different reference videos. Thus, in order to facilitate identifying new videos that include content of a reference video, the digest component 108 can generate digest information for one or more of the references video that uniquely identifies the reference videos as a whole and/or uniquely identifies one or more different slices or segments of the reference videos. For example, the digest component 108 can divide a reference video into two or more slices or segments, each respectively including parts of the video (e.g., one or more portions of the video having a duration less than the whole video). Accordingly, as used herein, the term “video” can also include slices or segments of a whole video.

In some implementations, the digest component 108 can generate digest information for slices or segments of the reference videos. In other implementations, the digest component 108 can determine whether and/or how to generate digest information for different slices or segments of a reference video based on one or more defined factors. For example, in one embodiment, the digest component 108 can generate reference digest information for two or more slices or segments of a reference video based on duration of the reference video, wherein longer videos are digested into a greater number of segments than the number of segments for shorter videos. For example, the digest component 108 can employ defined criteria based on the length of the reference video. In some embodiments, reference videos having a duration less than N can be digested as a whole; reference videos having a duration greater than N and less than M can be digested as two separate segments; reference videos having a duration greater than M and less than P are digested as three separate segments, and so on, wherein N, M, and P are numbers representative of numbers of video frames and/or numbers of seconds or minutes of a reference video. In another embodiment, the digest component 108 can generate reference digest information for different segments or slices of the reference videos based on a level of importance of the respective reference videos, wherein those reference videos that are considered more highly ranked than others are digested into a greater number of segments or slices. According to this example, the level of rank of a reference video can reflect a cost associated with the reference video, such as cost associated with protection against usage of the copyrighted content of the reference video. For example, a reference video that is associated with a high royalty payment in association with usage of content of the reference video may be classified as having a high importance level and thus digested into several segments or slices to facilitate increasing the probability of finding new videos that include content from only a portion of the reference video. In another embodiment, the digest component 108 can generate digest information for different segments or slices of reference videos based on a quality and/or technical complexity of the video (e.g., resolution, compression).

The manner in which the digest component 108 slices a reference video in association with generating digest information for the different slices or segments of the reference video can vary. In some implementations, the digest component 108 can slice a video into segments of equal duration. For example, a reference video that is two minutes long can be sliced at the one minute marker into two segments having substantially equal length durations. In another implementation, the digest component 108 can slice a reference video based on detection or identification of scene transitions (e.g., using tag metadata that was previously associated with the reference video or another suitable approach), wherein the video is sliced at the respective scene transitions. In another example implementation, the digest component 108 can slice a reference video based on detection of noteworthy or popular objects, scenes or events in the reference video (e.g., using tag metadata that was previously associated with the reference video or another suitable approach). According to this example, if a reference video includes a segment with an actor reciting a popular quote, the digest component 108 can generate first reference digest information for the segment in addition to generating second reference digest information for the whole reference video.

After the reference digest database 122 has been generated (e.g., by digest component 108 or another system or entity), the digital media management component 104 can employ the digest component 108 to generate digest information for new videos received by or otherwise provided to the digital media management component 104 (e.g., via reception component 106) for analysis regarding potential usage of reference video content in the new video (e.g., copyright infringement analysis). For example, based on reception of a new video, the digest component 108 can generate digest information for the new video that includes the same or a similar type of reference digest information as the reference videos. For instance, the digest component 108 can generate digest information for the new video that includes but is not limited to, objects appearing in the video, detailed characteristics of the objects (e.g., object coloration, object type, etc.), order of appearance of the objects, timing of appearance of the objects and/or spatial relationships between two or more objects appearing in a same frame or segment of the video. The matching component 114 can further compare the digest information for the new video with the reference digest information for the reference videos in the reference digest database 122 to determine whether the new video includes content of one or more of the reference videos based on a degree of similarity between the digest information for the new video and the reference digest information for the respective reference videos.

In one or more embodiments, the digest component 108 can include object recognition component 110 and timing component 112 to facilitate generating digest information for videos (e.g., reference videos, slices or segments of the reference videos, newly received videos not previously included in the reference digest database 122, slices or segments of the newly received videos). The object recognition component 110 can identify objects (e.g., persons, places, things) that appear in a video using hardware, software, or a combination of hardware and software that provides for automated detection of visual objects, appearing in video or digital image. Object recognition algorithms can rely on matching, learning, or pattern recognition algorithms using appearance-based or feature-based techniques. Techniques include, but are not limited to, edges, gradients, histogram of oriented gradients (HOG), Haar wavelets and/or linear binary patterns.

In various embodiments, the object recognition component 110 can identify objects appearing in a video using a variety of models, including, but not limited to, extracted features and boosted learning algorithms, bag-of-words models with features such as speeded-up robust features (SURF) and maximally stable extremal regions (MSER), gradient-based and derivative-based matching approaches, Viola-Jones algorithm, template matching, image segmentation and/or blob analysis.

In some implementations, the object recognition component 110 can determine detailed characteristics associated with identified objects to increase the accuracy of identifying matching objects included in a new video and a reference video. The detailed characteristics can include any potential characteristic about an object that can be discerned by the object recognition component 110. For example, the detailed characteristics can relate to a coloration of the object, a type of the object or an identity associated with the object. For instance, in addition to detecting a car appearing in a video, the object recognition component 110 can identify a coloration of the car, a make of the car, a model of the car, a year of the car, a license plate number of the car, etc. In another example, in addition to detecting a person appearing in a video, the object recognition component 110 can determine information such as the identity (e.g., name) of the person, the approximate height and weight of the person, the clothing worn by the person, etc.

In some implementations, the object recognition component 110 can identify one or more detectable objects appearing in a video. In other implementations, the object recognition component 110 can employ discriminatory techniques to reduce the amount (and/or associated processing time) of objects identified in a video yet still identify enough objects to generate a digest for the video that sufficiently distinguishes the video to facilitate copyright infringement detection. For example, in one embodiment, the object recognition component 110 can detect objects appearing in only a portion of frames or time segments of the video (e.g., wherein a time segment of a video can include one or more frames or seconds of the video less than the whole video). According to this example, the object recognition component 110 can identify objects appearing in N frames every M frames of the video (e.g., as single frame every ten frames of the video or frames). In another example, the object recognition component 110 can select random frames or time segments of the video to identify and/or characterize objects appearing in the video. In another example, the object recognition component 110 can select a restricted number (e.g., the top three) of the most prominent objects identified in each frame or time segment of the video. Still in another example, the object recognition component 110 can employ defined criteria regarding types of objects to target for identification that are considered better candidates for establishing a unique digest for the video (e.g., particular people with known identities, known landmarks of physical structures).

Timing component 112 can determine timing information related to timing of appearance of objects identified in a video. For example, the timing component 112 can determine when an object appears in the video (e.g., referred to herein as the “start time”) and/or when the object no longer appears in the video (e.g., referred to herein as the “stop time”) relative to the beginning and/or the end of the video (or video segment). Based on a determination of when respective objects appear in a video, the timing component 112 can determine an order of appearance of objects identified in the video. In addition, based on a determination of when an object appears and no longer appears, the timing component 112 can also determine the duration or length of appearance of the object. The timing component 112 can also determine, in some embodiments, the duration between appearances of different object in the video. For example, the timing component 112 can determine that a white dog appears in a video ten seconds after a blue car appears in the video. The timing information can be characterized in terms of time unit (e.g., milliseconds, seconds, minutes, etc.) and/or in terms of frames.

In some embodiments, in association with reception of a video, the digital media management component 104 can receive metadata associated with a video that includes one or more tags identifying previously identified objects appearing in the video and potentially timing of appearance of the objects. For example, a user uploaded video may be previously tagged with information identifying one or more actors appearing in the video, timing information regarding the appearance of the one or more actors, physical structures appearing in the video and associated timing information, geographical locations depicted in the video and associated timing information, etc. According to these implementations, the object recognition component 110 and the timing component 112 can respectively employ the metadata previously associated with the video to identify and characterize the objects appearing in the video and the timing of appearance of the respective objects.

FIG. 2 illustrates an example video 200 in which objects present in respective frames of the video have been identified (e.g., via object recognition component 110 and/or timing component 112 of FIG. 1) in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity.

The video 200 can include a plurality of frames 202 ₁-202 _(n) and has a duration of time T₀-T_(n). It should be appreciated that the number of frames included in a video can vary depending on the duration of the video and/or the frame rate of the video. For example, there are three main frame rate standards in television and digital cinema: 24 f6rames per second (FPS), 25 (FPS), and 30 (FPS). However, there are many variations on these as well as newer emerging standards (e.g., which can vary from 24 FPS to over 100 FPS). For ease of explanation, video 200 is described having a frame rate of 1 FPS. For example, the duration of time of T₀-T₁ is 1 second, the duration of T₁-T₂ is 1 second, and so on.

In the embodiment shown, objects A, B, C, D, E, and F have respectively been identified in frames 202 ₁-202 ₉ (e.g., via object recognition component 110 and/or timing component 112). The different letters A, B, C, D, E and F respectively describe different objects. Consecutive letters are used to indicate the order in which the different objects appear. For example, object A appears in frames 202 ₁-202 ₃, object B appears in frames 202 ₂-202 ₃, object C appears in frames 202 ₂-202 ₅, object D appears in frames 202 ₅-202 ₇, object E appears in frames 202 ₇-202 ₈, and object F appears in frame 202 ₈-202 ₉. Lines -A-, -B-, -C-, -D-, -E-, and -F-, respectively represent the timing and duration of appearance of objects A, B, C, D, E and F relative to one another in video 200 over time T₀-T₉. It should be appreciated that the number of different objects included in respective frames of a video (e.g., video 200) can vary. In addition, over the course of a video (e.g., video 200), some objects can re-appear. For example, another order of objects appearing in a video (e.g., video 200) can include A, B, C, A, D, A, E, B, B, E, E, A, etc.

Referring back to FIG. 1, matching component 114 can facilitate determining whether a new video received by the digital media management component 104 (e.g., not previously determined to be a reference video or associated with the reference digest database 122) is or includes video content included in one or more of the reference videos (including portions or segments/slices of the reference videos). In particular, the matching component 114 can determine whether a new video includes content included in one or more of the reference videos associated with the reference digest database 122 based on a degree of similarity between the digest information for the new video (e.g., as determined by digest component 108), and respective reference digest information for the reference videos. For example, the matching component 114 can determine that a new video includes content included in one or more of the reference videos based on the degree of similarity between the digest information for the new video and the digest information for the one or more reference videos satisfying a defined matching criterion (e.g., in various embodiments, the similarity level being above or substantially equal to a threshold value or percentage).

The matching component 114 can employ various techniques to determine a degree of similarity between digest information for a new video and digest information for a reference video. These techniques can vary based on the type of digest information associated with the respective videos, which can include one or more of objects appearing in the video, characteristics of the objects, order of appearance of the objects, timing of appearance of the objects and/or spatial relationships between two or more objects appearing in a same frame or segment of the video.

The matching component 114 can facilitate automated digital copyright detection substantially improving the processing efficiency among processing components in existing digital copyright detection systems, reducing delay in processing performed by the processing components and/or improving the accuracy in which the processing systems identify usage of copyrighted video content. For example, the matching component 114 can automatically identify videos that include copyrighted video content in a manner that cannot be performed by a human (e.g., using approaches that are greater than the capability of a single human mind). For example, the amount of data processed, the speed of processing of the data and/or the electronic data types processed by the matching component 114 over a certain period of time can be respectively greater, faster and different than the amount, speed and data type that can be processed by a single human mind over the same period of time. For example, video data processed by the matching component 114 can be raw data (e.g., raw audio data, raw video data, raw textual data, raw numerical data, etc.) and/or compressed data (e.g., compressed audio data, compressed video data, compressed textual data, compressed numerical data, etc.) captured by one or more sensors and/or one or more computing devices specially designed to obtain and process raw data and/or compressed data.

In some embodiments, the matching component 114 can determine a match between a new video and a reference video based on a degree in similarity between the objects appearing in the respective videos being above a threshold value. For example, a new video that includes a minimum defined percent of the same objects appearing in a reference video can be considered a match with the reference video. For instance, in an example embodiment in which video 200 of FIG. 2 is a reference video, the matching component 114 can determine that a new video that also includes objects, A, B, C, D, E and F is a match with the reference video. The threshold amount can vary (e.g., the minimum defined percent can be 75%, 85%, 90%, 95%).

The degree of similarity can also account for similarities and/or differences between detailed characteristics of the objects. For example, the matching component 114 can consider a car appearing in the new video as not being a match with a car appearing in the reference video because the cars are different models (or have differences in other visual features). The degree of scrutiny applied by the matching component 114 with respect to correspondence between objects can vary. In some embodiments, with respect to coloration of objects, for example, the matching component 114 can account for consistency in coloration differences between respective objects appearing in a new video and a reference video to determine whether the difference in coloration of the respective objects is attributed to an adaptation of coloration settings or an effect applied to the new video (e.g., the new video may be a black and white version of the reference video or the new video may have a blue undertone applied, a different saturation level, a different luminosity level). According to these embodiments, consistent coloration differences between the respective objects of the new video and the reference video would not affect the degree of similarity between the objects.

In some embodiments, the matching component 114 can also determine whether a new video includes video content of a reference video based on similarity in an order of appearance of the objects appearing in the new video and the reference objects appearing in the reference video. For example, the matching component 114 can determine a new video includes content of the reference video based on a determination that the order of appearance of the objects in the respective videos is the same or substantially the same (e.g., with respect to a threshold value or percentage). For example, in an embodiment in which video 200 of FIG. 2 is a reference video, the matching component 114 can determine that a new video that also includes objects, A, B, C, D, E and F (in that order) is a match with the reference video. According to this implementation, a new video can be a modified version of the reference video and can have removed some of the objects included in some frames of the reference video and/or can have added (e.g., as an overlay) new objects to some frames of the reference video. However, despite this modification, the remaining common objects of the new video and the reference video will still likely be in the same order. Thus, although the degree of similarity between objects appearing in the new video and objects appearing in a reference video can be reduced based on editing applied to the reference video to create the new video, the matching component 114 can still determine that the new video includes content of the reference video based on a combination of the amount of common objects between the respective videos and/or the degree of similarity in order of appearance of the common objects.

In some embodiments, the matching component 114 can further determine whether a new video includes video content of a reference video based on timing of appearance of objects in the new video and corresponding objects appearing in the reference video. This timing of appearance information can include the start times of the respective objects, the end times of the respective objects, the duration of appearance of the respective objects and/or the timing between appearances of different objects (also referred to as “difference in start times of object pairs”).

For example, the matching component 114 can identify a string of objects included in the new video that are also included in a reference video in the same order. The matching component 114 can further align the start times of one of the objects in the string for the new video with the start time of the corresponding reference object of the string for the reference video (e.g., the first object in the respective strings). For instance, in an example embodiment in which video 200 of FIG. 2 is a reference video, if the new video and the reference video both include objects A, B, C, D, E and F in that order, the matching component 114 can align (in time) the start times of object A in both videos and then determine whether the start times of objects B, C, D, E and F are also aligned in time. If the new video includes content of the reference video, the start times of objects A, B, C, D, E and F in both videos should align if there is a match(e.g., if the new video has not been sped up or slowed down).

In some embodiments, the matching component 114 can also determine whether the durations of appearance of the respective objects in both videos align. For example, in an embodiment in which video 200 of FIG. 2 is a reference video, the matching component 114 can determine that a new video that also includes objects, A, B, C, D, E and F match with the reference video if, in addition to including objects A, B, C, D, E and F in that order, and both videos having aligned start times for objects A, B, C, D, E and F, the duration of appearance of objects A, B, C, D, E and F in both videos is approximately the same (e.g., if the new video has not been sped up or slowed down). For instance, if object A appears in the reference video for three consecutive frames, object A should appear in the new video for three consecutive frames if there is a match. According to this example, the matching component 114 can determine that a new video includes content of a reference video based on a degree of similarity in the start times of respective objects included in both videos and/or the degree of similarity in the duration of appearance of the respective objects being above or substantially equal to a threshold value.

In another example, the matching component 114 can identify a string of objects included in the new video that are also included in a reference video in the same order. The matching component 114 can determine whether differences between the start times of pairs of objects in the string of the new video correspond with differences between the start times of the corresponding pairs of objects in the string of objects in the reference video.

FIGS. 3A and 3B provide graphical depictions of example digest information for a reference video and a video including content of the reference video in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity.

For example, FIG. 3A provides a graphical depiction of example digest information 300 for video 200 in accordance with one or more embodiments described herein. The digest information 300 for video 200 can include information indicative of an order, timing and/or duration of appearance of identified objects A, B, C, D, E and F relative to the beginning and the end of the video, as represented by lines -A-, -B-, -C-, -D-, -E-, and -F- in relation to one another. The digest information 300 for video 200 can also include the duration or length of time between the start times of different consecutive objects (e.g., identified via the dashed lines). For example, the length between the start times of objects A and B is L₁, the length between the start times of objects B and C is L₂, the length between the start times of objects C and D is L₃, the length between the start times of objects D and E is L₄, and the length between the start times of objects E and F is L₅.

With reference to FIGS. 1 and 3A, in furtherance to the above example wherein both the new video and the reference video include objects A, B, C, D, E and F in that order, the matching component 114 can compare the length of time between the start times of objects A and B, B and C, C and D, D and E, and E and F for both the new video and the reference video (e.g., L₁-L₅). If the length between the start times of the respective pairs of objects is the same (e.g., if the new video has not been sped up or slowed down), the matching component 114 can determine that that new video likely includes content of the reference video. According to this example, the matching component 114 can determine that the new video includes content of the reference video based on a degree of similarity in the differences between the start times of the corresponding object pairs included in the new video and the reference video being above a threshold value.

The matching component 114 can also employ timing of appearance information regarding correspondence between start times of respective objects appearing in a new video and a reference video, correspondence between durations of appearances of the respective objects, and/or correspondence between difference in start times of corresponding pairs of the objects, to determine when a new video includes content of a reference video yet simply has a modified duration relative to the reference video based on speeding up or slowing down of the reference video content. For instance, a length of two minutes in between the start times of objects A and B appearing in the reference video can be considered a match against a length of 1 minute and 45 seconds between the start times of objects A and B appearing in the new video if the new content video was sped up by 12.5%.

Likewise, if the length of time of appearance of object C in the reference video is 30 seconds, the length of time of appearance of object C in the new video would be 33 seconds if the speed of the new video was reduced such that the duration of the new video is 10% longer than the reference video. Accordingly, in some embodiments, the matching component 114 can determine a relative ratio or percentage representative of the difference in duration between the start times of a pair of objects appearing in both the new video and the reference video, or a relative ratio or percentage representative of the difference in duration of appearance of an object appearing in both the new video and the reference video. The matching component 114 can further determine that the new video and the reference video match or substantially match based on a determination that the start times of additional corresponding object pairs in the new video and the reference video or the durations of appearance of additional objects in the new video and the reference video, consistently differ by the relative ratio or percentage. Thus, the matching component 114 can determine that content of a new video matches that of a reference video if the relative lengths between the start times of object pairs appearing in both videos or the relative durations of appearance of corresponding objects in both videos are the same in view of the new video being sped up or slowed down.

FIG. 3B provides a graphical depiction of example digest information 301 for a new video in accordance with one or more embodiments described herein. As exemplified via comparison of digest information 300 and digest information 301, the new video can include the same or similar content as video 200, yet the new video has a shortened duration (d) relative to video 200 due to an increased speed of the new video relative to the speed of video 200. For example, similar to video 200, the digest information 301 for the new video includes information indicative of an order, timing and duration of appearance of identified objects A, B, C, D, E and F relative to the beginning and the end of the video, as represented by lines -A-, -B-, -C-, -D-, -E-, and -F- in relation to one another. The digest information 301 for the new video substantially corresponds to the digest information 300 for video 200; however due to an increased speed of the new video relative to video 200, the length of time between the start times of different consecutive objects A and B, B and C, C and D, D and E and F, L₁′-L₅′, is shorter relative to L₁-L₅, respectively. However, assuming for example, the ratio of L₁′/L₁ is 90%, in some embodiments, the matching component 114 can determine that the new video includes content of video 200 if the ratios of L₂′/L₂, L₃′/L₃, L₄′/L₄ and L₅′/L₅ are also 90%, respectively (or within a defined range of 90%). It should be appreciated that the length of time between any two endpoints of lines -A-, -B-, -C-, -D-, -E-, and -F- can also be employed to facilitate determining correspondence between relative timing of appearance of objects in video 200 and the new video. For example, the lengths between start times of objects A relative to the end times of object D in both videos can be compared to determine whether they differ by a same percentage as the lengths between the end times of object C relative to the end time of objects F, and so on.

FIG. 4 illustrates a chart 400 including example digest information for video 200 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity.

In the embodiment shown, the digest information identifies the objects that appear in the video and the order of appearance of the objects over time T₀-T₉. It should be appreciated that the digest information can span a longer duration of the video (e.g., T₀-T_(n), wherein n is the last frame of the video), and that digest information for only a portion of the video is presented merely for exemplary purposes. The digest information also includes the start times of appearance of the respective objects, the end times of appearance of the respective objects, the length of appearance of the respective objects (e.g., in number of frames or seconds), and the lengths (e.g., L₁-L₅) between the respective start times of different consecutive objects (e.g., in number of frames or seconds).

FIG. 5 illustrates another block diagram of an example, non-limiting system 500 that facilitates detecting usage of copyrighted video content using object recognition in accordance with one or more embodiments described herein. System 500 includes same or similar features and functionalities as system 100 with the addition of spatial recognition component 502 and filter component 504 to digital media management component 104. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity.

In various embodiments, the digest component 108 can include spatial recognition component 502 to determine spatial relationships between different objects appearing in a same frame or segment of a video (e.g., wherein a segment can include a plurality of consecutive frames). In some implementations, the spatial recognition component 502 can identify relative sizes of objects appearing in the same frame or segment of a video. For example, a segment of a surfing video can include a surfer in the forefront of the frame riding a wave on a red surfboard with a yellow boat in the distance. According to this example, the spatial recognition component 502 can determine the size of the red surfboard relative to the size of the yellow boat. In another implementation, the spatial recognition component 502 can determine relative positions of two or more objects appearing in the same frame or segment of a video relative to a two-dimensional or three-dimensional coordinate space. For example, with respect to a rectangular frame and a two dimensional coordinate space wherein the bottom region of the frame corresponds to an x-axis and the left side of the frame corresponds to a y-axis, the spatial recognition component 502 can determine coordinates corresponding to the positions of the objects appearing in the frame relative to the coordinate spaces. In some embodiments, the spatial recognition component 502 can further determine distances between two or more objects appearing in the same frame or video segment of a video.

For example, FIG. 6 illustrates another example of video 200 with objects present and in which spatial relationships of objects present in respective frames of the video have been identified (e.g., via spatial recognition component 502) in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity.

In particular, in addition to identifying objects A, B, C, D, E and F respectively appearing in frames 202 ₁-202 ₉, the objects are respectively depicted in circles having a determined size (e.g., diameter) and location in the frame. For example, frame 202 ₃ includes three circles for objects A, B and C respectively having different sizes and locations in the frame.

FIG. 7 illustrates another chart 700 including example digest information for video 200 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity.

In the embodiment shown, the digest information identifies the objects that appear in respective frames 202 ₁-202 ₉ of the video. The digest information also includes coordinates of the respective objects in the frames relative to a two-dimensional coordinate space, wherein the respective frames have a rectangular shape and the x-axis corresponds to the bottom region of the respective frames and the y-axis corresponds to the left side of the respective frames. For those frames including two or more objects (e.g., frames 202 ₁, 202 ₃, 202 ₅, 202 ₇, and 202 ₈), the relative size ratio of the objects to one another can be also identified.

In some embodiments, information regarding spatial relationships between two or more objects appearing in a same frame or segment of a video can be added to the digest information for the video to facilitate identifying usage of reference video content in another video. For example, matching component 114 can determine whether a new video includes content of a reference video based on both videos including two or more of the same objects appearing in a same frame or segment and having a same or relatively the same spatial relationship. Because the spatial relationships between two objects appearing in a same frame or segment of a video do not change if the dimensions of the video frame or segment are modified, digest information regarding spatial relationships between two or more objects appearing in a same frame or segment of a video can facilitate identifying new videos that include reference video content in a manner that modifies the frame size of the reference video content. For example, a new video can include the surfing video in the example above playing on a television in the background while a group of surf instructors provide commentary on the surfing video. According to this example, although the content of the surfing video does not make up the entirety of the frame dimensions, the relative sizes and positions of the red surfboard relative to the yellow boat will be the same (or approximately the same), thus facilitating detection of the usage of the surfing video content in the new video.

Referring back to FIG. 5, in various embodiments, the matching component 114 can employ one or more analysis techniques that account for the degree of similarity between digest information for a new video and a reference video with respect to a combination of the various types of digest information described herein, including, but not limited to, objects appearing in the video, detailed characteristics associated with the objects (e.g., object coloration, object type, etc.), order of appearance of the objects, timing of appearance of the objects (which includes relative timing to account for new videos that have been sped up or slowed down) and/or spatial relationships between two or more objects appearing in a same frame or segment of the video.

In some implementations, the matching component 114 can determine a match score that accounts for a total degree of similarity between a new video and a reference video with respect to a combination of one or more of the factors previously noted. For example, a new video can have a 75% degree of similarity with respect to shared objects, a 90% degree of similarity with respect to order of appearance of the shared objects, a 95% degree of similarity with respect to timing of appearance of the shared objects, and 100% degree of similarity with respect to spatial relationship between two or more of the shared objects appearing in the same frame or segment of the video, resulting in a match score of 90% degree of similarity.

In some embodiments, the matching component 114 can also apply different weights to the respective factors that are determined to have a higher impact on matching accuracy (e.g., timing of appearance of objects versus number of corresponding objects). The matching component 114 can further employ a threshold requirement wherein new videos having a match score greater than a defined value can be considered a match with the reference video.

In some embodiments, the matching component 114 can employ filter component 504 to facilitate enhancing the efficiency with which the matching component 114 determines whether a new video includes reference video content (e.g., using processor 118 or another processor). For example, rather than scanning a new video against every entry in the reference digest database 122 with respect to each type of digest information category, the matching component 114 can employ the filter component 504 to reduce the number of potential candidate reference videos to evaluate more thoroughly. For example, the filter component 504 can apply one or more first filtering criteria that reduce the set of reference video in the reference digest database 122 to a smaller subset of potential matches. The matching component 114 can further evaluate the subset of the reference videos with respect to one or more second criteria. In an example, the filter component 504 can apply a hierarchy filtering scheme, wherein the filter component 504 first identifies a first subset of the reference videos having at least a first defined percent of shared objects with a new video. The filter component 504 can then reduce the first subset of the reference videos to second subset of reference videos based on a degree of correspondence between an order of appearance of the shared objects being another threshold value. In some embodiments, the matching component 114 can further evaluate the second subset of reference videos based on correspondence between timing of appearance of the respective objects and/or degree of similarity between spatial relationships of two or more of the shared objects appearing in a same frame or segment of the new video and the reference videos.

In another example embodiment, the matching component 114 can evaluate a video for potential usage of reference video content by employing the filter component 504 to apply a first filter that identifies a subset of the reference videos in the reference digest database 122 having at least a defined number of corresponding objects to an evaluated video and appearing in a same order as the evaluated video. According to this example, the subset of the reference videos can include reference videos that have different amounts of corresponding objects depending on the amount of reference video content included in the evaluated video. For example, the evaluated video can include a short segment of a long reference video and thus include only a small subset of objects appearing in the reference video. In another example, the evaluated video can include objects removed from the reference video content. In yet another example, the evaluated video can include added objects overlaid on reference video content.

In some embodiments, the matching component 114 can further isolate only the matching objects between the video and the respective reference videos in the subset and determine whether other factors including, for example, timing of appearance of the matching objects, specific details of the matching objects or spatial relationships of two or more matching objects appearing in a same video frame or segment, respectively correspond (e.g., either exactly or relatively in consideration of a modified timing of the video, a coloration effect applied to the video, or a modified frame size of the video).

FIG. 8 illustrates a block diagram of another example, non-limiting system 800 that facilitates detecting usage of copyrighted video content using object recognition in accordance with one or more embodiments described herein. System 800 includes the same or similar aspects as system 500 with the addition of publication component 802, notification component 804 and compensation component 806 to digital media management component 104. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity.

In various embodiments, in response to a determination that a new video does not include media content included in reference video, the digest component 108 can add information identifying the new video and digest information for the new video to the reference digest database 122. The new video can thus become a new reference video in some embodiments. In some implementations, the notification component 804 can generate and/or transmit a notification (e.g., using an electronic message or other notification approach) to an entity affiliated with the new video (e.g., an entity affiliated with the new video can be a human or electronic uploader of the new video). The notification can inform the entity that the new video does not include reference video content (e.g., copyrighted).

In an embodiment in which the server device 102 is or is affiliated with a media content provider (e.g., a video sharing and streaming service, a social networking system that provides for sharing or video content), the digital media management component 104 can process a new video with respect to detecting usage of reference media content in association with a request to publish the new video via the media content provider. According to this embodiment, in response to a determination that the new video does not include reference video content, the publication component 802 can proceed to publish the new video on a network accessible platform (e.g., a website, an application, etc.) employed by the media provider to distribute the media content.

The digital media management component 104 can further facilitate mitigating the unauthorized use of reference (e.g., copyrighted) video content. For example, in an embodiment in which a video including reference video content is associated with a request to publish the video, the publication component 802 can automatically reject publication of the video on the network accessible platform employed by the media provider and/or, in some embodiments, the notification component 804 can generate a notification that informs an entity associated with use of the video (e.g., an uploader of the new video) that the video is or includes reference video content. In some implementations, the notification can identify the reference video content and indicate a match score determined by the matching component 114 regarding the degree of similarity between the video content and the reference video content.

In another embodiment, in response to a determination by matching component 114 that a video is or includes reference video content, the notification component 804 can generate and/or transmit a notification to an entity associated with ownership of the reference video content (e.g., the copyright holder, a licensee of the copyright holder). The notification can inform the entity regarding usage of the reference video content, identify the video that is or includes the reference video content, and/or identify the entity associated with creation or usage of the video. In some implementations, the notification can include contact information for the entity associated with usage and/or creation of the video.

In various additional embodiments, compensation component 806 can facilitate providing entities associated with ownership of reference video content (e.g., the copyright holders, licensees of the copyright holders) compensation for usage of their reference video content by others. For example, in one implementation, in response to a determination (e.g., by matching component 114) that a particular video is or includes reference video content, the compensation component 806 can facilitate provision of a royalty payment to the entity that owns the reference video content. For instance, the compensation component 806 can charge the user associated with upload of the particular video a defined royal payment that accounts for the manner in which the user employed or is intended to employ the reference video content.

While FIGS. 1, 5 and 7 depict separate components in the digital media management component 104, it is to be appreciated that two or more components can be implemented in a common component. Further, it is to be appreciated that the design of the digital media management component 104 can include other component selections, component placements, etc., to facilitate identifying usage of reference (e.g., copyrighted) video content and mitigating the unauthorized usage of the reference video content. Moreover, the aforementioned systems and/or devices have been described with respect to interaction between several components. It should be appreciated that such systems and components can include those components or sub-components specified therein, some of the specified components or sub-components, and/or additional components. Sub-components could also be implemented as components communicatively coupled to other components rather than included within parent components. Further yet, one or more components and/or sub-components can be combined into a single component providing aggregate functionality. The components can also interact with one or more other components not specifically described herein for the sake of brevity, but known by those of skill in the art.

Further, some of the processes performed may be performed by specialized computers for carrying out defined tasks related to the digital media copyright detection subject area. The subject computer processing systems, methods apparatuses and/or computer program products can be employed to solve new problems that arise through advancements in technology, computer networks, the Internet and the like. The subject computer processing systems, methods apparatuses and/or computer program products can provide technical improvements to automated digital copyright detection systems by improving processing efficiency among processing components in digital copyright detection systems, reducing delay in processing performed by the processing components, and improving the accuracy in which the processing systems identify usage of copyrighted video content.

FIG. 9 illustrates a flow diagram of an example, non-limiting computer-implemented method 900 that facilitates detecting usage of copyrighted video content using object recognition in accordance with one or more embodiments described herein. At 902, a system operatively coupled to a processor determines digest information for a video, wherein the digest information comprises objects appearing in the video and respective times at which the objects appear in the video (e.g., via digest component 108). At 904, the system compares the digest information with reference digest information for reference videos, wherein the reference digest information identifies reference objects appearing in the reference videos and respective reference times at which the reference objects appear in the reference videos (e.g., via matching component 114). At 906, the system determines whether the video comprises content included in one or more of the reference videos based on a degree of similarity between the digest information and reference digest information associated with one or more of the reference videos (e.g., via matching component 114). For example, the system can determine that the video includes reference video content based on digest information for the video and the reference video indicating that the respective videos include a substantial amount (e.g., with respect to a threshold value) of common objects, the common objects appear in both videos in a substantially same order (e.g., with respect to a threshold percentage) and/or the timing of appearance of the common object in both videos is substantially the same (e.g., with respect to a threshold value or range of time values).

FIG. 10 illustrates a flow diagram of another example, non-limiting computer-implemented method 1000 that facilitates detecting usage of copyrighted video content using object recognition in accordance with one or more embodiments described herein. At 1002, a system operatively coupled to a processor determines digest information for a video, wherein the digest information comprises objects appearing in the video and respective times at which the objects appear in the video (e.g., via digest component 108). At 1004, the system compares the digest information with reference digest information for reference videos, wherein the reference digest information identifies reference objects appearing in the reference videos and respective reference times at which the reference objects appear in the reference videos (e.g., via matching component 114). At 1006, the system determines that the video comprises first content included in a first reference video of the reference videos based on a degree of similarity between the digest information and first reference digest information of the reference digest information for the first reference video being greater than a threshold degree of similarity (e.g., via matching component 114). At 1008, the system mitigates unauthorized usage of the first based on the determining that the video comprises the first content included in the first reference video (e.g., via publication component 802, notification component 804 or compensation component 806). For example, the system can reject a request to publish the video on a network. In another example, the system can notify an entity associated with ownership of the first reference video regarding the video, the usage of the reference video content in the video, the degree of similarity between the video content and the reference video content, and/or contact information for the user and/or creator of the video. In another example, the system can facilitate providing the entity associated with ownership of the reference video a royalty payment by the user of the video.

FIG. 11 illustrates a flow diagram of another example, non-limiting computer-implemented method 1100 that facilitates detecting usage of copyrighted video content using object recognition in accordance with one or more embodiments described herein. At 1102, a system operatively coupled to a processor determines digest information for a video, wherein the digest information comprises objects appearing in the video and respective times at which the objects appear in the video (e.g., via digest component 108). At 1104, the system compares the digest information with reference digest information for reference videos, wherein the reference digest information identifies reference objects appearing in the reference videos and respective reference times at which the reference objects appear in the reference videos (e.g., via matching component 114). At 1106, based on the comparing, the system identifies a first reference video of the reference videos comprising at least some first reference objects that correspond to the objects in the video and that occur at first respective reference times in the reference video similar to the times at which the objects appear in the video (e.g., via matching component 114). At 1108, the system identifies a base time length separating two of the objects appearing in the video at different times. For example, with reference to FIGS. 3A and 3B, assuming digest information 301 represents digest information for the video of method 1100 and digest information 300 represents digest information for the first reference video of method 1100, the system can identify any length between two end points of lines -A-, -B-, -C-, -D-, -E-, and -F- as the base length, such as L₁′. At 1110, the system identifies a reference time length separating two first reference objects of the at least some first reference objects corresponding to the two of the objects appearing in the video. For example, with reference to FIGS. 3A and 3B, if the system selects L₁′ as the base time length, the system will select L₁ as the reference time length. At 1112, the system can further employ a ratio of the base time length relative to the reference time length to determine whether the video comprises first content included in the first reference video of the reference videos. For example, the system can employ the ratio of L₁′/L₁ to determine whether additional lengths between other objects appearing in the video (e.g., L₂′, L₃′, L₄′, and L₅′) and corresponding lengths between other reference objects in the reference video (e.g., L₂, L₃, L₄, and L₅) respectively and consistently differ by the ratio. Accordingly, the system can identify (e.g., via matching component 114), new videos that include sped up or slowed down versions of reference video content.

FIG. 12 illustrates a flow diagram of an example, non-limiting computer-implemented method 1200 that facilitates detecting usage of copyrighted video content using object recognition in accordance with one or more embodiments described herein. At 1202, a system operatively coupled to a processor, determines digest information for a video, wherein the digest information comprises objects appearing in the video and an order in which the respective objects appear in the video (e.g., via digest component 108). At 1204, the system compares the digest information with reference digest information for reference videos, wherein the reference digest information identifies reference objects appearing in the reference videos and reference orders in which the respective reference objects respectively appear in the reference videos (e.g., via matching component 114). At 1206, the system determines whether the video comprises content included in one or more of the reference videos based on a degree of similarity between the digest information and reference digest information associated with one or more of the reference videos (e.g., via matching component 114).

The descriptions of the various embodiments have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
